Was able to use purchased product a couple times before an out of state vacation. Since returning, I have had two more golf dates that product was used and performed as it should. This was an exact replacement for same style rangefinder I have used over past 6 years, which was a Christmas gift from my son. In early July, my original Bushnell Phantom was fully charged, but would not activate to search the course I was playing. Fortunately, fellow golfer kept me informed on distances needed.
